VIII. Enhanced Management and Diagnostic Capabilities
Finisar Smart SFP CWDM transceivers can be used in the typical network configuration
shown below:
The Smart SFP’s built-innon-intrusive optical communication channel enables remote
monitoring and management. Through the I2C interface, the host equipment can manage
not only the local Smart SFPs, but also the Smart SFPs located at the far end. These
enhanced functions are available by following “Finisar Smart SFP Host Interface
Specifications”
With Finisar’s Smart SFPs, equipment vendors can achieve the following advanced
management and diagnostic capabilities:
Remote Smart SFP digital diagnostics
Optical link monitoring
Optical dying gasp for fault isolation. With optical dying gasp when power
failure is imminent, the far-end Smart SFP will quickly generate adying gasp
signal to the near-end Smart SFP on the other end. The near-end equipment can
thereby distinguish between far-end power failure and optical cable cut.
